Gents,
Completed the job with no issues. I used a 7" piece of vacuum hose to thread the new plugs into the heads. Then slipped a 5/8" plug socket (with the rubber retainer removed) into each plug seat to tighten to around 15 lbft. Only one you need to be careful with is good old #8. I held the plug socket against he valve cover and popped on the 3/8" drive universal joint (actually used two but really only needed one) then eased the socket down onto the plug. Worked like a charm. When recovering the socket, just reversed the process and held the socket against the valve cover, removed the universal and recovered the socket.
Fired up the engine. All good. Will take it out for a WOT pull when the weather clears here in Houston..
